Struct fastly::error::BufferSizeError

pub struct BufferSizeError {
    pub buf_size: usize,
    pub needed_buf_size: usize,
    pub buffer_kind: BufferKind,
}

Insufficient buffer size error.

This is returned by methods like RequestHandle::get_header_names() if a value was larger than the provided maximum size.

If you get such an error, you can try the same call again with a larger buffer.

Fields

buf_size: usize

The attempted buffer size.

This is to help make nicer error messages.

needed_buf_size: usize

The buffer size that was required.

Trying an operation again with a buffer at least this big may succeed where a previous call failed. However, it is not guaranteed to succeed, for example if there is an even larger value later in the list than the first value that was too large.

buffer_kind: BufferKind

The buffer kind whose size was insufficient.

Trait Implementations

impl Clone for BufferSizeError

fn clone(&self) -> BufferSizeError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BufferSizeError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for BufferSizeError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for BufferSizeError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
